如图,由题意知,“Given that ”汉语意思是“已知”,“prove that”汉语意思是“求证”. 延长BE交AC于N,则: ∵ \, BE⊥ AE, ∴ \, ∠ AEB=∠ AEN=90^(° ). ∵ \, ∠ 1=∠ 2,AE=AE, ∴ \, △ AEB≌△ AEN. ∴ \, AB=AN,BE=NE,∠ 3=∠ 4. ∵ \, ∠ 4=∠ C+∠ 5, ...
解析 22 (1) It is easy to prove that quadrilateral CEDF is a parallelogram, and since CD bisects ∠ACB, we can get that quadrilateral CEDF is a rhombus. (2) It can be proved that quadrilateral CEDF is a rectangle, so ∠BCA =90°. Therefore, AC^2+BC^2=AB^2 . ...
